Houdini 17.0 Nodes VOP nodes

If Connected VOP node

Passes through the value of the first input if the first input is ultimately connected.

This operator passes through the value of the first input if the first input is ultimately connected. If the first input is not ultimately connected, it outputs the value of the second input. If neither input is connected, the operator outputs the value specified in the Defaults section of the operator parameters.

An input is not ultimately connected if it has no immediate link, or if it has a link that comes directly from a Subnet Inputs operator, and the parent subnetwork has no corresponding input connection, or that connection is also a Subnet Inputs operator, and so on.

Thus, if an input is directly connected to a Subnet Inputs operator, it is not considered to be ultimately connected unless the parent network provides an ultimately connected link to it.

This operator is effectively a combination of two operators: an Is Connected test followed by a Two Way Switch.

Examples

The following examples include this node.

FlipColumn Example for FLIP Solver dynamics node

This example demonstrates how a mixture of fluid colours can have their colour changed by a collision with a static object.

AlphaOmega Example for Points from Volume geometry node

This example demonstrates how to use a Points From Volume SOP to create a target goal for a flip simulation and make it fill a given piece of geometry.
